Three-year experience with a wireless ECG sensor

The success of performing long-term ECG measurements depends on how much the device is interfering with the user. A small and unobtrusive sensor on the skin in conjunction with a smartphone today presents a viable option because such a configuration allows also online access to cardiac services. Despite the limited choice of electrode placement, it has been shown that the ECG sensor may replace the ambulatory ECG (Holter ECG) in many cases. In this paper, we present our experience on setting up an ECG sensor to obtain the best information about heart arrhythmias. We also add experience in unconventional use of the sensor in abdominal ECG and recommendations for the future use of such devices.
